Last Names of Nuevo Leon

It is amazing the work that Crispin Rendon along with many giving volunteers have been able to accomplish. Slowly but surely we are moving forward in a good direction.

Yesterday Crispin emailed everyone on his mailing list the following report which I find truly Amazing and informative. In the future anyone that tests their mtDNA and matches that of Ricardo Valdez can with certainty state that they too have Tlaxcaltecan ancestry.

Here are Crispin’s introductory description of the report and also the mtDNA results of this particular line.

This report documents the 10 generation mtDNA line of Ricardo Valdez. This line extends to Native Americans of the Tlaxcalteca tribe. Most of our citizen science project mtDNA lines are Native American. This is the first to extent at least 10 generations and also be identified by tribe. Special thank you to Ricardo for sharing his research and test results. All images from

  1. I had my father tested with FamilyTreeeDNA but have not yet uploaded a tree as i need to go thru and create a new one and verify all source information. How do i go about finding out what members of this group have matched up if any for my dad.

  2. Maria Concepcion Cadenas DOD was transposed from 1957 to 1975. This was a fascinating read. Confusing at times but amazing to have been able to go so far back. Thanks for sharing.
